Right. I think I can guess what's going on here, and it's not pretty.
For various reasons, Rabbit can have the same file open multiple times.
It can then decide to delete that file. Under unices, that's not a
problem. However, apparently in general, on Windows, you can't ask for a
file to be deleted if it's held open.
This is not going to be a simple thing to fix. In all honesty, the best
solution right now is for you not to run Rabbit under Windows. If you
have to use a Windows host, then run a Linux VM within it.
I'm pretty astonished that this hasn't been reported before. I guess
that's likely an indication of the number of people that run RabbitMQ
